Major cryptocurrency exchanges<\/a> Bitfinex and OKEx are reeling from bouts of distributed service denials<\/strong> that were orchestrated over the last 24 hours.<\/p>\n <\/p>\n OKEx was the first to experience the DDoS<\/strong> (distributed denial of service) at approximately 11:30 AM EST on Thursday 27th<\/sup>. OKEx CEO Jay Hao posted<\/a> on the attack on his Weibo page blaming unnamed competitors of his exchange\u2019s woes.<\/p>\n At the time, the attackers routed 200 gigabytes per second of traffic to the OKEx servers, an amount that they could not handle and therefore crippling any legitimate website traffic from accessing the servers.<\/p>\n Following this occurrence, OKEx underwent a system maintenance operation on Friday morning that was scheduled to last a reported 40 minutes. On Friday, OKEx published<\/a> a notification on the then-upcoming maintenance writing that,<\/p>\n \u201cfeatures of the market quote, order placement, order cancellations, order amendments could be affected for Futures (Coin-margined Futures, USDT-margined Futures), Options Trading. The system maintenance will impact users of the website, APP, the desktop client and API access.\u201d<\/em><\/p>\n <\/p>\n Once the maintenance exercise was concluded, OKEx was hit again by the second round of DDoS attacks and this time, the attacker routed double the traffic rate (at 400 GB\/s).<\/p>\n It was around this time, at approximately 4:30 AM EST on Friday morning that Bitfinex was also hit by a similar attack<\/a> <\/strong>which has made the community to suspect a common attacker. According to Bitfinex\u2019s status page, it seems the attack lasted an hour during which there was hardly any throughput on the website servers.<\/p>\n As of press time, both exchanges are reporting<\/a> that the services are back to normal and none of their customers have suffered any direct financial losses.<\/p>\n
